Size It Up game is Magnitudle's daily size comparison game for visual reasoning. Five object comparisons make up one daily run, and every round can award up to 100 points for a maximum of 500. The game belongs to Magnitudle's wider daily estimation family, alongside Pop Culture and Geography variants. It rewards a proportion that looks right, not a typed measurement guessed from memory.
How to Play Size It Up game: Read the Scale
Controls
Use the fixed blue reference as the anchor, then read the dotted guide to see whether the round is asking for height or length. The measurement itself remains hidden, so the silhouette is your only visual clue. Move the red target into a useful position and resize it with the corner handle; on mobile, pinch with two fingers. Zoom out if a larger estimate needs room, then lock in to see the true scale and round result.
Game Features
- Five-round daily visual scale run
- Fixed blue object to anchor each comparison
- Red silhouette with move and resize interaction
- Height or length cue shown by dotted guide

Use the corner handle on desktop or pinch with two fingers on mobile to resize the red target, following the dotted guide for the dimension marked in the current round.
How many rounds are in the daily game?
The daily challenge contains five comparisons. Lock In each estimate to reveal its result, then continue through the remaining rounds for a total possible score of 500.
